Whoever believes that Jesus is the Christ is born of God, and everyone who loves Him who begot also loves him who is begotten of Him. 2 By this we know that we love the children of God, when we love God and keep His commandments. 3 For this is the love of God, that we keep His commandments. And His commandments are not burdensome. 4 For whatever is born of God overcomes the world. And this is the victory that has overcome the world—[a]our faith. 5 Who is he who overcomes the world, but he who believes that Jesus is the Son of God? The Certainty of God’s Witness 6 This is He who came by water and blood—Jesus Christ; not only by water, but by water and blood. And it is the Spirit who bears witness, because the Spirit is truth. 7 For there are three that bear witness [b]in heaven: the Father, the Word, and the Holy Spirit; and these three are one. 8 And there are three that bear witness on earth: the Spirit, the water, and the blood; and these three agree as one. 9 If we receive the witness of men, the witness of God is greater; for this is the witness of [c]God which He has testified of His Son. 10 He who believes in the Son of God has the witness in himself; he who does not believe God has made Him a liar, because he has not believed the testimony that God has given of His Son. 11 And this is the testimony: that God has given us eternal life, and this life is in His Son. 12 He who has the Son has [d]life; he who does not have the Son of God does not have life. 13 These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life, [e]and that you may continue to believe in the name of the Son of God.

By this we know love, because He laid down His life for us. And we also ought to lay down

our lives for the brethren.But whoever has this world’s goods, and sees his brother in need, and shuts up his heart from him, how does the love of God abide in him?

My little children, let us not love in word or in tongue, but in deed and in truth.And by this we [a]know that we are of the truth, and shall assure our hearts before Him.For if our heart condemns us, God is greater than our heart, and knows all things.Beloved, if our heart does not condemn us, we have confidence toward God.And whatever we ask we receive from Him, because we keep His commandments and do those things that are pleasing in His sight.And this is His commandment: that we should believe on the name of His Son Jesus Christ and love one another, as He gave us commandment.

Now he who keeps His commandments abides in Him, and He in him. And by this we know that He abides in us, by the Spirit whom He has given us.
